Are the motore speeder 7.3 and/or 8.3 tour spec models still available as an "off-menu" item? I did not see them in the shaft performance guide, but I believe they were previously available off-menu. If they are still available, would I be able to purchase either shaft individually through an authorized retailer? I recently purchased a new 917 F3 15* which was custom ordered from Titleist through my local retailer, but am wanting to also purchase one of the Speeder .3 models to put in my new 917 F3. Thanks in advance.
